p'l'et'ed. Theseotions thus superiinposedone upon the other 'are unitedtogether and form ay continuous wall' of uniform appearance.

A furtherr feature of the invention jiiesidesf in the provision of a'type-ol" building-form whereby a ldouble wall maybe erected andtiedto'getlier in suoli a manner tliatlthewalls.

, between the bearings 5, and thecorresponding mold board until saidrespective mold boards 1 and 2 are the proper distance apart to give therequired'thickness yto they round notches 13, 13,'in the upper edge of`each course, as formed.v

The anchoi` plates 3, 4, have upwardly diverging slots v14, 14 and the'wedges 8, 9 also havev upwardly diverging slots 15, 15.

l These upper ends of the slots 15 overlap the lower-.f en ds of thecorresponding slots 14, when theV Wedges are in Vlower position..

Vhen it is desired to elevate l.the forms, keys as l'are driven throughsaid slots, as illustratedin Figure 2, to force them into regisf teringposition. This will elevate the Wedges and release the anchor plates andthe entire form maythen be elevated. `The forms are elevatedv until themold-boards do not quite clear the upper edge ofthe completed section ofthe wall, and tie rods as 17 are laid Vvtransversely. with theirrespective ends resting in opp'ositenotches of the completed wallsections 18, 13, and the molds are then lslightly lowered until thekinner mold boards 2, 2, rest on said rods, the lower edges of said moldboardshaving notches 19, 19, to re# -ceive the rods, as indicatedinFigure 1. The molds are 'thus supported while another course of the wallis being poured.

The plastic Vmaterial ofthis additional course is then poured and willrun into and harden in the bottom notches 13, 13, to asf sistin unitingthe superimposed sections to-V gether, andthe rods 17, 17 also tie theouter and inner wallstogether. Itis to be also Vunderstood that verticalreinforcing rods (not shown) will be embedded in each course and theupper ends of these rods will project above said course and be embeddedin lthe `course jabovewhen it is poured v,toV tiethe superimposedsections together in the' usual Way.

, When heavy forms are used a derrick may be erected for a block andtackle (not shown) to be used in the usual way for .lifting said forms.The derrick shown consists of the uprights 20, 20, having the crownblock 21 for an obvious purpose'. rights may be provided with the lugs22,22, if desired for engagement over the tie rods 17 to support the,derriclL If light ,formsl are used, a lifting bar may be Vinsertedthrough the bearing slot 23.
